DEVICE FOR HOLDING AND CLA MPING PAPERS, 80c.

SPECIFICATION forming part of Letters r tentlvo ssnei 2, dated December25,1894. Application filed October 1,1894. Serial No. 524,568. (Nomodel.) I

act description, reference being had to the drawings which accompany andform a part I ofthis specification, in which Figure 1 is a perspectiveview of one of my paper holding clamps, one side longitudinally andvertically cutaway, to show the working parts beneath, along the dottedline no of Fig. 7, and showing also, in dotted outline other workingparts beneath the supporting board, A. Fig. 2 is a longitudinal sectionshowing Fig. 1 with the board depressed upon its spring support, and itsclamping jaw raised and tilted up for the reception of papers. Fig. 3 isa perspective view of the working parts, the springs, C O, and theboard, A, removed. Fig. 4 is a longitudinal vertical section of my paperholding clamp, in which the position of the clamping jaw is reversed,for holding papers when perforated, and the construction somewhatmodified for such purpose. Fig. 5 is a similar view to that shown inFig. 4 with the board depressed upon its spring'supportand the clampingjaws open for the reception of papers. Figs. 6, 6 and 6" are views indetail of the devices I prefer to use for attachment of my supportingspring or springs to the board, A; and Fig. 7 isatop view, through theboard, A, which is shown in dotted outline, of the working parts of mydevice when modified as described.

The lettering in all the figures is uniform. My invention relates to theconstruction of devices for clamping and holding papers and the'like ofthe general class shown in United States Letters Patent of G.BernardPetsche, No. 405,596, and bearing date June 18, 1889, in which a boardorother support rests at one end upon a desk or table, or is hung on anail, and rests against the wall, the other end being raised andsupported upon a flexible spring, so that when considerable pressure isapplied to the top surface. of said board, near its upper or freemargin, the spring will yield and thesupported end thereof be depressed,

the middle layer, a

said movement of depression serving to actuate mechanism automaticallywhereby the clamping jaws are forced open, against spring pressure so asto permit the insertion of loose sheets of paper, and when the pressureis re leased, the action of said spring, as the free end of the boardrises, will again force down the said clamping jaws andgrasp and holdsaid papers.

The construction which forms the subject matter of my present inventionembracescertain advantages of cheapness, and efficiency' of operation,and capability of being modified to'suit certain special requirements inuse, which differentiates it from said patented invention, and for whichI desire to secure Letters Patent.

'A is a board which may be of plain Wood, but for which I prefer to usea special construction of material, as it is essential to the operationof this device that the lower margin of said board and its free edgealong the clamping surface should be flat and not warped, or the devicewill tilt to and fro and interfere with its use in writing upon the papers held therein. For this purpose I use a board built up in layers,and glued together, so that the grain of the wood of the two outerlayers, a and a shall run across the grain of More than three layers maybe used if desired, but three give the best results in my experience. Iuse this board finished with varnish, or the like, along the edges, butnot supported in panels, or doweled to marginal strips, the edges beingfree, as cut. These boards may-have a width of six, eight, or twelveinches, and a length of twelve, fifteen or more, according to thedimensions of the papers to be clamped. I

usually round the corners somewhat to avoid scoring the table upon whichthe devicemay be used. At or near its raised upper part I pivot one ortwo bell-crank clamping arms, 3 B, having a rise, 13', nearest the pointof 1mpjingement upon the board of the clamping jaws, B, to clear theboard and give room for .the papers, and a downwardly extended portion,Bat the bottom of which is the pivot,

B by which the said clamp is secured'to the pivot support, A, of theboard, A. The clamping arm is continued beneath this pivot at an angle,either backwardly, as in Figs. 1, 2 and 3, or forwardly, as in Figs. 4,5, and 7, ex.- tending along beneath the free or raised margin of theboard, A, longitudinally, so that, when downward pressure is applied tothis raised end of the said board, the free angular ends of the clampingjaw will engage upon a fixed support below, and the said clamping jawwill be rocked upon its pivoted support, A" B which will cause theclamping ends of said jaw or jaws, B, to be raised from said board inthe arc of a circle, upon B A as a radius, and form an opening intowhich papers may be inserted between said clamping jaw and said board.To compress this clamp, and support the raised free end of thesupporting board, the spring 0 is employed. This spring may be of anyform desired, flat, coiled, or angular, and may be secured in variousways, but I prefer to use the construction shown, in which the spring orsprings, O, are of fiat metal, and secured at one end to the under sideof the board, A, so as to allow the free end, extending to the frontraised end of and beneath the said board, A, to be vibrated under springtension. These springs may be attached directly to the free under armsof the clamping jaws, forming their bell-crank extensions, B B whichwill thus rest upon the table and form the support for the free raisedend of the board, A; but in such case these arms will grind by theirextremities upon the table beneath, even if provided with rollers, asthey may be, or else will cause slip of the board when it lies upon thetable, since the distance from the unsupported margin of the board, uponthe table, to the pivot, A, and thence to the end of the bell crank arm,is greater than a straight line along the table between the said points.To avoid this I prefer to secure the free ends of the springs, C, O, toa preferably wooden cross bar, E, to the upper surface of which they areattached by screws, s s, Fig. 7, and I make this bar, E, cylindrical inform, so that as the springs are compressed it will correspondin glyrotate upon the table and thus avoid the difficulty described. To thisbar, E, I secure the hearings or bell'crank attachments which actuatethe clamping jaws. In Figs. 1, 2 and 8 I use a small link, D, secured atone end to an eye, F, of the plate, F, which secures the spring, 0, tothe bar, E, which gives a very free movement, while in Figs. 4, 5 and 7I merely run the bell-crank arm through a sleeve between the plate, F,and the cross bar, E, shown at F so that the angular-distance is takenup by play on the bar, E, instead of on the table, T. The plate, F, Iprefer to extend along the bar, E, the distance between the springs, CC, when I use two springs, which I do not always do in narrowconstructions, as they thus insure accuracy of spacing, and also affordslide bearings for the bellcrank arms, B of the clamping jaw. In themiddle portion I form this plate, F, with a loop, F thus producing ahandle by which thewhole device may be hung up on a wall, as it operatesquite as well in this position as when horizontal. At F I also show acentral rise in the plate, F, forming a socket into which engages, whendesired, the bolt, G, see Figs. 4, 5 and 7, whereby the device may beheld open to remove and tile papers away, when the perforating holder isused instead of a simple compression clamp. This bolt I make to work sofree in its keeper, G, that by merely turn ing the device in one way oranother, with the spring, 0, compressed, it will drop in or out of therecess, F The forward end of the bolt, G, is bent downward and thenforward as shown at G Fig. 4, to permit it to enter thesocket freely,and a small stud, in rear prevents its escape. The small screws, 9 g,secure the keeper to the under side of the board, A. To secure the rearend of the spring, 0, to the board, A, a simple perforation may be used,and a screw, 0 G, as shown in Fig. 6; but to insure a strong strain Iuse the device illustrated in detail in Figs. 6 and 6". When twosprings'are used, as in Fig. 6" I join the spring holders, 0 C by acrossbar, 0 so as to maintain distance, as is done by the correspondingplate, F, at their forward end. This bar, 0 also assists instrengthening the board, A. A small metal casting open through, at C,and having a raised forward edge, a is provided with a pin, C cast on,and projecting upward toward the board, A. Screw holes, C, enable thisholder to be secured to the under side of the said board, as shown inFig. 6. The perforation, c, at the end of the spring, 0, is hooked on tothe pin, 0 and its forward end is then drawn down, after the screw, 0has been applied, and secured to the bar, E, and the clamp, B, securedto the same holds all in place under strong tension, the spring, 0,being strained over the raised edge, 0

In Figs. 1, 2 and 3 the bell-crank pivot, 13, of the clamping arm is atthe extreme front of the board, A, and the clamping jaws extend to therear, which is the margin which rests directly upon the table; but inFigs. 4, 5, and 7 the clamping lever is reversed, and is seated in aslot, or slots, A in the board A. I usually use two of these clamps, asshown in Fig. 7. They are cast flatwise, or

otherwise formed, and have pivot supports,

B B Fig. 7 which rest ,upon the board, A, alongside the slots, A and arecovered and held down by the rearward extension, B A, Figs. 4 and 5,grooved transversely for their reception, and thus forming a pivotbearing. The forward free ends of these clamping jaws are separatelypointed as shown in Fig. 6,and above these points I prefer to form eyes,B, whereby a cord may be inserted and the perforated papers drawn off,when the bolt, G, is locked, and tied up in bundles, by means of saidcord or string.

To insure perforation, I provide a raised seat, A preferably of castmetal, at the forward end of A, in which are openings, 0. for thereception of the points, 13, as shown, which when impaled they are drawnforward around the looped or raised parts, B B of the clamping arm, whenthey will lie fiat upon the board A, face side uppermost. I also modifymy device in various other ways without departing from the principles ofmy invention.
